Unless you are experimenting, you should not use it. The very last things in the library were implemented in GCC 14? But no doubt some bugs remain, of course. Other than the library GCC 12 was feature-complete already? And GCC 11 was *almost* there (most C++20 things were implemented during GCC 8 and GCC 9 development). Well, there are still some module things wanting, but that is true for *any* compiler, so no project depends on that either! There has not been ten years of experience with GCC C++20, so yeah it is still experimental in that sense, but so is C++20 per se! Segher
